Hello, Clojureverse!
Since I started learning Clojure, I tried different development environments, including Eclipse and LightTable, but today, I am back to the simplest-thing-that-could-possibly-work: VIM.
I started with Eclipse with counterclockwise. It has syntax highlighting and a REPL and it was OK when I worked on my first Clojure project: clogo, a LOGO turtle interpreter. (I’ll surely come back on this one). It certainly does the job, but I would not really recommend Eclipse for Clojure… too heavyweight.
After installing Leinigen and using VIM for a short period of time, I stumbled onto LightTable, which is clean and nice, with a minimalistic design. It seemed promising as it includes a REPL with real-time evaluation of the Clojure code you type. But I found it not very practical, because unlike an autocompletion feature, I like my REPL to wait until I’m done typing. So I ended up copying and pasting code from LT to my REPL, which I thought was probably not the best way. (The other thing that I didn’t like about LT is that the screen could only be split vertically; maybe it’s improved today).
In quest of a more integrated environment, I went back to VIM and tried the NailGun server for REPL integration. It is OK, and although the execution of Clojure code in a separate window seemed a good idea, it looks like NG is sometimes getting lost when I inadvertently close it’s buffer. That’s really a pain.
At this point, I found vim-fireplace (earlier called foreplay.vim) which is simple and really nice. It will find your REPL and automatically connect to it, and it can not only execute a block of code in a single keystroke, but also run your tests, or let you see the documentation for any function.
So to summarise: my environment today is Leiningen, and MacVim with vim-fireplace (+ vim-clojure-static and rainbow_parentheses.vim plugins). I am using clojure.test for testing, and cloverage to measure my test coverage. And I use criterium library together with VisualVM when I have to look at performance.
Voilà. Enough talking. Let’s start coding…
